Research and engineering verification of high-voltage cal?le laying method under complicated working conditions

摘要

In the light of the characteristics of the cable construction model under complicated working conditions, it is found that there is no engineering experience to calculate the traction force of the stay tube section and the arc high drop section. This paper establishes the corresponding engineering mechanics models according to the construction site environment, which determines the engineering calculation formulas by theoretical deduction and the on-site industrial test verification, thus realizing the safe, economical and efficient laying of high-voltage cables under complex working conditions. Finally, the 220kV East Traction Station project is taken as an example to verify the proposed construction scheme. The results show that the laying and bending tasks can be successfully completed and all the indicators are in perfect conformity with the technical specifications.
